High-voltage power lines carry electricity all over the country. These lines are not invincible. They take regular maintenance and repair. But getting that done is no small feat.

In this video, you’ll meet an incredible repairman. He is flown out to the jobsite on a helicopter. He then climbs onto the high-voltage power lines. And, believe it or not, the lines are still active.

But wouldn’t he get electrocuted? Actually, he’s shielded by simple physics. He uses a device invented in the early 1800s. I could go on, but I think he explains it best. Watch the video. It’s fascinating!

We’ve run this clip before. It got a great response. So, we’ve brought it back. Enjoy!
